GENERAL DESCRIPTION OF SYSTEM EXTENSION AND PROJECT SCHEDULE 1.0 Overview The System Extension plan will focus on extending the life of the existing CCCS radio system by systematically replacing end-of-life equipment in strategic phases culminating in an upgrade to P25 compliance with the goal of continuing to provide quality radio communications to the law, fire, lifeguard and public works agencies in Orange County. 2.0 Description of System Extension 2.1 System Backbone — Radio infrastructure equipment that is at or near the end of its expected life will be directly replaced with the current version of the same equipment that will maintain all existing features and fimotionahties and is able to work with the existing backhaul network. Specifically, this will involve the replacement of 565 +existing Quantar radio base stations and ancillary equipment at 25 radio sites with 800 MHz 3600 baud GTR8000 base stations and ancillary equipment. This will be accomplished in accordance with the following schedule: System Backbone schedule: Northwest Cell = 24 Quantars replaced in 2015 Southwest Cell = 40 Quantars replaced in 2015 Laguna Cell = 33 Quantars replaced in 2016 Moorhead IR Site = 8 Quantars replaced in 2016 North Cell = 105 Quantars replaced in 2016 South Cell = 135 Quantars replaced in 2017 Crystal Cove IR Site = 4 Quantars replaced in 2017 Countywide Cell = 210 Quantars replaced in 2017 Carbon Canyon IR Site = 3 Quantars replaced in 2017 Silverado IR Site = 3 Quantars replaced in 2017 2.2 Law Enforcement Dispatch Consoles — Police Dispatch Gold Elite consoles will be out-of-service by the vendor in 2018 and will need to be replaced prior to 2018 to maintain the existing console priority feature once the system is upgraded to P25. Console priority is a feature unique to law enforcement dispatch and allows dispatch to have the ability to transmit and receive audio simultaneously and is an officer safety necessity. Existing Gold Elite Console equipment will be replaced with its successor console; the MCC7500. Due to the complexity of the replacement at each law dispatch center, only 6 dispatch centers can be upgraded each year. A schedule has been developed to address the 20 law dispatch centers on the system, as shown below. Page 8 of 11 55A -15
